The Luna G3 CPAP Machine is one of the most popular devices from React Health, formerly known as 3B Medical Inc. As a continuous positive airway pressure machine, the device is designed to maintain a constant level of air pressure during the entire breathing cycle.
The Luna G3 CPAP Machine offers many premium features aimed at providing a more comfortable CPAP experience, including a built-in humidifier, integrated heated tubing, and a preheat function. The machine also has an automatic ramp setting that gradually increases the pressure, allowing you to ease into CPAP therapy.
There are several options in the Luna G3 product line. The Auto CPAP model automatically adjusts the air pressure by monitoring your breathing patterns for sleep apnea events. The Luna G3 BPAP 25A and Luna G3 BPAP 30VT are both bilevel positive airway pressure (BiPAP) machines that provide different pressure levels for inhalation and exhalation.
We’ll focus on the CPAP model, covering its features, performance, technical specifications, and who might be a good fit for the device.
Other Models in the Luna G3 Series
- Luna G3 Auto CPAP: Like the standard Luna G3 CPAP Machine, the G3 Auto CPAP comes equipped with a continuous positive airway pressure mode. However, the latter also features an automatic positive airway pressure (APAP) setting that automatically adjusts the pressure level based on the user’s breathing patterns.
- Luna G3 BPAP 25A: This versatile model has both CPAP and APAP functions but also includes a BiPAP mode that increases pressure during inhalation and decreases it during exhalation. It also has an auto BiPAP mode that automatically adjusts for apneic events.
- Luna G3 BPAP 30VT: This Luna model offers a CPAP mode and the same two BiPAP therapies offered by the 25A, though it lacks an APAP function. Instead, the 30VT includes two additional BiPAP modes. One is a timed mode that toggles between the inhalation and exhalation pressure settings at a set rate based on breaths per minute. The other uses Luna’s forced ventilation technology, which automatically delivers airflow if it detects that the user hasn’t inhaled within a set period of time.
What You Need to Know About the 3B Luna G3 CPAP Machine
Obstructive sleep apnea (OSA) is a condition involving intermittent periods of breathlessness or paused breathing during sleep due to narrowed or blocked airways. The condition is common, affecting 10% to 30% of U.S. adults.
CPAP machines pull in surrounding air and pressurize it to a specific level based on the user’s prescription. The air passes through tubing connecting the machine to a CPAP mask, where it enters the airway, making breathing easier.
Most CPAP machines measure pressure in centimeters of water pressure (cm H2O). The Luna G3 CPAP Machine has a 4 to 20 cm H2O range, which can be set in increments of 0.5 cm H2O. The device also has integrated heated tubing and a built-in humidifier with a preheat function that helps moisturize the air. These elements are designed to help prevent hose and mask condensation and reduce potential side effects such as dry mouth and dry nasal passages.
Another selling point of the Luna G3 is its ramp feature. The machine starts with lower pressure and gradually increases it to the prescribed pressure level to ease the user into their nightly therapy.
Like all PAP devices, purchasing the Luna G3 CPAP Machine requires a prescription. Speak with your doctor if you think the device is right for you.

Features You Might Like
The Luna G3 CPAP Machine has several features aimed at making the treatment of OSA more comfortable and user-friendly. These include adjustable ramp settings, humidity controls, heating options, and an easy-to-use interface.
- Adjustable ramp setting: The ramp feature allows you to start therapy at a lower pressure setting and slowly build to your prescribed pressure over a period of time you set. Many CPAP users find this gradual pressure buildup less jarring. The time period is customizable up to a maximum of 60 minutes.
- Humidity controls: The built-in humidifier helps to reduce nasal dryness and irritation by adding moisture to the pressurized air. There are five humidity levels available.
- Heating options: The preheat function enables you to warm the water in the humidifier tank for up to 30 minutes before use. The integrated heated tubing helps to prevent condensation from forming in the tubing and mask.
- LCD interface: The digital interface has an LCD screen and a single control knob to navigate the machine settings. You can view sleep data, such as your nightly usage score, and transmit that information to your doctor. Additionally, the machine provides replacement reminders for the air filter, connective hose, and face mask.
CPAP Machine Size and Cost
Measuring 10.4 inches across by 5.7 inches deep and 4.5 inches tall, the Luna G3 CPAP Machine is compact enough to fit on most nightstands. The humidifier’s water chamber holds a maximum of approximately 12 fluid ounces.
Weighing in at about 3.75 pounds, the device is comparable to other CPAP machines with built-in humidifiers. While it’s heavier and bulkier than most travel CPAP machines, it’s still small enough that it won’t take up too much space in a suitcase.
The price of the Luna G3 CPAP Machine is on par with other CPAP-only models with built-in humidification systems.

How This CPAP Machine Performs
The LCD screen and single-knob operation make the Luna G3 user-friendly. The ability to program preheat settings and the ramp function add to the overall user experience.
The Luna G3 is designed to be compatible with almost any CPAP mask. The device’s connective tubing works whether you prefer a full-face, nasal, or nasal pillow mask.
The pressure settings for the Luna G3 span from 4 to 20 cm H2O, which is the standard range for most CPAP machines. The pressure can be increased in 0.5 cm H2O increments.
The sound level of the Luna G3 CPAP Machine is around 26 decibels when the pressure is set at 10 cm H2O. This makes it quieter than most CPAP machines, which have an average sound level of 30 decibels.
The ability to preheat the water in the humidifier tank and the heated tubing keeps the air warm, which makes breathing easier for many CPAP users. The Luna G3 features an AutoHumidity option that adjusts the humidity levels based on the room climate. Keeping the humidity at the right level helps prevent rainout, which is when condensation builds up inside the mask and tubing.
According to the manufacturer, the Luna G3’s tubing and water chamber should be cleaned daily. Use distilled water to fill the water chamber after it’s been washed and dried. Other accessories, including the mask, should also be cleaned daily per manufacturer instructions.
The machine’s cleanable components and other accessories should be washed with warm water and mild soap. Typically, the filter needs to be replaced every six months. Store the machine and its accessories out of direct sunlight.
While the Luna G3 CPAP Machine wasn’t created specifically for travel, it’s still relatively small and light and should fit in most carry-on bags. The water chamber can be removed before traveling to make the machine more compact. However, travelers should note that this model is not approved by the Federal Aviation Administration for in-flight use.
